# Primers with Rstudio

.infobox.assignment[ **Objective**

- This tutorial will learn you the basic skills to understand R languages.
You will need in each analysis: how to inspect, visualize, subset, and transform your data, as well as how to **run code** with the basic functions.

We'll concentrate our attention to this final element, How to **run code** and the basic functions.
